Vortex Energy Corp. has successfully completed a high-resolution magnetic survey at the north block of the company’s Robinsons River Salt Project in southwestern Newfoundland, using a UAV (unmanned aerial vehicle).
Conducted by EarthEx Geophysical Solutions, the survey marks the next step in advancing exploration in the region.
The UAV survey utilized cutting-edge technology to acquire high-resolution magnetic data across three target areas, with 25-meter line spacing and precise terrain-following capabilities. The results successfully identified magnetic anomalies that reveal structural features across various parts of the project. These findings suggest that magnetic surveys may be able to effectively distinguish subsurface structures relating to salt formations suitable for cavern storage development.
The success of this survey demonstrates the value of magnetic studies in mapping structural features and supports the case for expanding geophysical exploration at the Project. Future magnetic studies, combined with complementary techniques such as seismic and gravity surveys, could further refine the understanding of salt deposit occurrences and enhance targeting for cavern storage potential.
The image below shows the location of the magnetic surveys in the project area.
